I don’t need this right now. I really, honestly don’t. Without cracking the hood I want to say it’s a coil plug or, god forbid, an injector. They’re all original to the car which means they’re 19 years old and have done 260,000 miles. I doubt it’s as simple as a spark plug because those are all less than a year old with fewer than 6k on ‘em.
So that raises the question: do I want to trust an aftermarket coil or injector? Because if I’m doing one I should really replace all of them at the same time, and doing that with OEM parts will be prohibitively expensive.
Coils run from $50/ea for OEM to $100 for genuine BMW. Aftermarket ones are $15-30/ea.

My thought is typically will the damage done by the failed cheap part exceed the amount needed to fix it properly.
A coil? Sure, throw 30 bucks.
An injector? Ill go above to not do that again.
Swap coils around, throw some seafoam at the situation, and see if your day improves is how my buddy in a skyactiv 3 has handled the situation.

Had a couple coils go now, I assume it’s those.

At 260,000, you might take a few minu te s do a compression test before throwing parts at it. It is probably a coil pack or an injector , but there’s no reason not to make sure an old engine isn’t down a cylinder before throwing money at a mis fire.

It honestly depends on if the car is worth it. If you have a garbage minivan like me (which only has about 3 breakages per month), I would advise you to just let it kill itself. But if it holds a high value and has almost no chance of destroying another crucial part, then by all means go for it.
